To all whom-.itmcy, concern;

Be it known that I, HERMANN Wlmgn, a subject of the. German Emperor,residing at 'Elfbuchenstrasse 12, Cassel, Germany, have invented a. newand useful Process of Providing Bread and other Baked Articles with aProtective Covering, of. which the following is a specification.

This invention relates to aprocessof providing bread and other bakedarticles with a protective covering.

. According tov this invention the dough is inserted in a coveringadapted to be closed on all sidesand is baked together with thecovering. A stiflt' greased vegetable fiber paper is ,used as thecoverin which paper is intended as a substitute or the smooth doughshell or covering worked by hand, and before using. the bread can bereadily removed therefrom.

In the performance of the process, the dough on removal from the.kneading machine .is separated into pieces and each piece of. dough isinserted in an oil-sheet covering, the desired form being.simultaneously given to the dough. The bread rises and is baked in thiscovering and is kept therein. The covering thus protects the, bread fromimpurities during its production and storage, especially from contactwith the. hand.

A machine for performing the process is'sho'wn diagrammatically by way.of example in the accompanying drawings in wh1ch Figure 1 is an endviewpartly in section through the dough feeding devices while Fig. 2is afront elevation. Fig. 3 is a section on an enlarged scale on the line BBof Fig. 1. Figs. 4. and 5 show the table on an enlarged scale in planand in end view respectively. Fig. 6 is asection on the line AA of Fig.4. Fig. 7 is a section on the line DD of- Fig. 6. Fi s. 8 and 9 showdetails on an enlarged sca e.

The dough is fed by the feeding worm 2 driven by the main shaft 1, fromthe kneading trough 3 to the outlet 4, in'. front of which an endlessband 7 running over rollers 6 in a table 5 takes up the dough as itleaves the trough. The table 5 is rotatable from its horizontal positionin the direction of the arrow 2 about the axis 10 on the rail 9, themovement being limited by a stop 11. A device 12 movable and adjustableabove the table serves for measurin'z which can then be separated fromone another by a blade 13 and on the tipping of the. table the piecesofdough will fall into the compartments ofa dough carrier. This doughcarrierconsists of-a basepla'te 14 with pins 15 on which is suspended aframe con- 'sisting of elastic cords 16. T0 the cords are parallel.double metal sheets 17 secured spaced at equal. distances behind oneanother, which on contraction or. extension of the cordsmove toward oraway from one another. The dough coverings 18 are pushed along. thesheets in such manner that they rest on the. base plate and form aninclosure; when all the inclosures are filled the cord frame is releasedand all the sheets are drawn away from the coverings, in whicl thepieces of. dough remain. The dough .carrier is mounted with pins 19above the holder 20 filled with oil in which it can be dipped by meansof a hand crank 21 in order both to lubricate the coverings and thestrips.

The device 12- for measuring off the lengths of dough consists of twoplates 22 i and 23 which are guided on rails 26. These rails are eitherfirmly secured or can be loosely suspended by pins 27 28 beneath the.mouth of the dough outlet 4 at the front end thereof. The. curvedbridge 29 connecting the. rails attheir outer ends carries ascrew-threaded spindle 23 by means of .which the plate 23 is moved andadjusted. 'The movement of the plate 22. corresponds with that oftheplate 23, the plate 22 being resiliently connected with the frame andbeing also carried by pins 30. The machine operates automaticallyv insuch manner that after determination of the length of. dough, the rollof dough controls the device 12 whlch engages the clutch for effectingthe rotation of the blade which cuts the dough "and causes it to betitled into the. receiver of the dough carrier, whereupon. on itsfurther rotation the movement for. feeding the dough carrier. commences.Forward motion of the dough carrier is then interrupted momentarily, thenext receiver being brought into position to receive the piece of doughnext to fall.

According to the detailed drawing, Fig. 8,-a friction cone 31 isarranged at the end of the feeding shaft which may be moved by thetransverse pin 33 lying in the slot ofi thelengths of the several piecesof dough 32 in the shaft against the casing 34 loosely mounted on theend of the shaft and can be coupled therewith. The sliding movement ofthe friction cone actuates a rod or the like 35 lying in theaxialdirection of the shaft and guided through a central orifice till itreaches the pin 33 to which it is connected, the other end of which rodis adjustably connected with the curved part of the handle projectingbeneath the rails 9, 26. The casing 34 carries the blade 13 which iscarried with it by the shaft 2; as soon as the roll of dough moves backthe spring-controlled plate 22 and through the intermediary of the rod35 couples the friction cone 31 with the casing 34, the blade ing theoil holder or dough carrier. As

soon as the dough carrier is moved forward the width of a receiver, atooth of a rack 43 provided on the oil holder breaks the connection. Inorder that the blade may only cut through the roll of dough when thelatter has issued the required length and that on the other hand it maynot drop back into the position of rest, two members are used whichautomatically bring the beginning and end of the cycle into agreementwith the modus operandi of the machine.

According to Fig. 6 the left side of the front wall of the feeder ispartly covered. In the cover 44 is provided an opening 45 in whichenters the end of a rod 46 adapted to be adjusted on and fixed to theplate 22,

and prevents rotation of the blade until it is raised from the plate 22.At this moment the bolt 47 operated by a spring closes the opening 45and retains the rod until the blade 13 on its return with the nose 36abuts on the knob 48 of the lock and moves this aside whereby theopening is freed. The rod is pushed by the plate into the opening 45,while simultaneously the rod 35 moves along the feeding shaft anddisengagesthe connection between the friction cone 31 and the bladecasing 34. The knife and other baked articles, cutting the dough intosections of suitable remains in this position, as its return movement isprevented by a resilient stop 49 which is forced aside by the rotatingblade and after passage of the 'blade returns to the locking position.

I claim:

1. The process of manufacturing bread and other baked articles, whichconsists in completely inclosing the dough in a paper covering, andbaking the dough within the closed paper covering, substantially asdescribed. I

2. The process of manufacturing bread and other baked articles, whichconsists in completely inclosing the dough in a paper covering, bakingthe dough within the closed paper covering, and maintaining the bakedbread within said closed paper covering until used, substantially asdescribed.

3. The process of manufacturing bread and other baked articles, whichconsists in. cutting the dough into sections of suitable length,completely inclosing each section on allof its sides in a'papercovering, and baking the dough Within the said paper covering,substantially as described. I"

4. The process of manufacturing bread and other baked articles, whichconsists in completely inclosing the dough within a covering consistingof oiled paper, and baking the dough within such covering, substantiallyas described.

5. The process of manufacturing bread which consists in length,completely inclosing each section of dough on all of its sides in acovering consisting of oiled vegetable fiber paper, and baking the doughwithin such closed cover ing, substantially as described. f

6. The process of manufacturing bread and other baked articles, whichconsists in cutting the dough into sections of suitable length,completely inclosing each section of dough on all of its sides in acovering consisting of oiled vegetable fiber paper, baking the doughwithin the said covering of oiled vegetable fiber paper, and maintainingthe baked bread in such covering until .used, substantially asdescribed.

In testimony whereof I afiix my signature in presence of witnesses.
